Abstract
The utility model discloses a kind of rotary-vane vaccum pump, comprise vacuum pump body, described vacuum pump body bottom is fixed by supporting base, described vacuum pump body top one side connects suction tude bottom, described suction tude top is provided with suction port, described vacuum pump body top opposite side connects outlet pipe bottom, described outlet pipe top is provided with relief opening, described vacuum pump body top is also provided with oiler, described oiler is located between suction tude and outlet pipe, described vacuum pump body bottom one side is provided with oil outlet, a closed cavity of the inner formation of described vacuum pump body, in described closed cavity, be provided with rotor, described rotor is provided with blade.The utility model has the advantages that: blade is easy-rupturing not, overall structure is simple, easy to operate, increases working life, reduces the input of cost, is convenient to promote the use of.
Description
Technical field
The utility model relates to vacuum pump, relates in particular to a kind of rotary-vane vaccum pump.
Background technique
In rotary-vane vaccum pump definition pump, eccentric rotor and the stator stationary plane of installing is tangent, and two (or more than) blades slide and contact with stator inner wall in rotor, and a kind of rotary volume-variable that pump chamber is divided into several variable volumes amasss vacuum pump.Conventionally, the gap between blade and pump chamber is used as sealing with oil, so sliding vane rotary vacuum pump is generally oil seal type oil-sealed rotary pump.Its operating pressure scope is 101325-1.33 × 10-2(Pa) belong to Roughing pump.It can use separately, also can be used as the fore pump of other high vacuum pump or ultrahigh vacuum pump.It has been widely used in metallurgy, machinery, military project, electronics, chemical industry, light industry, oil and medicine etc. and has produced and scientific research department.It is one of pumping equipment the most basic in vacuum technique.Blade of the prior art is easily subject to excessive resistance and ruptures, and is easily corroded, and increases the input of cost.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in prior art.
Model utility content
The utility model provides a kind of rotary-vane vaccum pump.
The technical solution adopted in the utility model is:
A kind of rotary-vane vaccum pump, comprise vacuum pump body, described vacuum pump body bottom is fixed by supporting base, described vacuum pump body top one side connects suction tude bottom, described suction tude top is provided with suction port, described vacuum pump body top opposite side connects outlet pipe bottom, described outlet pipe top is provided with relief opening, described vacuum pump body top is also provided with oiler, described oiler is located between suction tude and outlet pipe, described vacuum pump body bottom one side is provided with oil outlet, a closed cavity of the inner formation of described vacuum pump body, in described closed cavity, be provided with rotor, described rotor is provided with blade.
Described rotor is eccentric rotor, and described blade equal angles is fixed on rotor.
On described blade, be less than the width near rotor-end away from the width of rotor-end.
On described blade, be coated with respectively polymer composite with closed cavity inwall.
The utility model has the advantages that: blade is easy-rupturing not, overall structure is simple, easy to operate, increases working life, reduces the input of cost, is convenient to promote the use of.
